Answer:

Solutions x= 9 and -9

Step-by-step explanation:

x^2-55=26

x^2=55+26

x^2=81

(take square root of both sides)

x=9

(squaring negatives is the same as squaring the same positive)

x also=-9

Answer:

x= 9 x= -9

Step-by-step explanation:

Equation: x^2-55=26

Move -55 to the other side - x^2=55+26 = X^2 = 81

Solve - x^2=81 - 9^2 = 81 and -9^2=81 (a negative squared becomes a positive)

Well, we know the last three numbers are:

The next set is:

9 (thousands)
3 (ten thousands)
0 (hundred thousands)

And finally:

6 (millions)

So we know that 5 is in ten millions.
